Dynamic Metal‐Organic Tube Isomers
Abstract
Abstract Preparing artificial assemblies that can achieve multi‐stimuli‐responsive and multi‐level transformations remains a huge challenge. Here, a pair of dynamic metal‐organic tube isomers was prepared from a ligand with multiple coordination modes and flexible conformations. They can undergo multi‐level transformations in response to different types of stimuli, including conformational isomerization driven by physical factors (e.g., concentration, temperature, and polarity), adaptive deformations driven by neutral guests, adaptive reconstructions induced by anionic templates. Notably, the guest‐driven deformed tubes can continue to undergo reconstruction induced by the PF 6 − template, and DMSO can simultaneously serve as a physical factor and a chemical template to continuously regulate isomerization and reconstruction of the dynamic tube. The dynamic tube can be used to regulate the stacking modes of encapsulated 1‐formylpyrene and 1‐acetylpyrene through adaptive deformations, thereby generating stable guest radicals, enhancing guest fluorescence and achieving white light emission.
